patent count has been increasing quickly in the last 5 years. The performance of
Japan is particularly impressive as it ranks first in terms of both patent count and
assignee code count. Nevertheless, inventors from the European Union have more
patents on average; each inventor in the Netherlands has 195 patents, in France
170, and in Germany 129. Each inventor from the United States, the United
Kingdom, Japan, South Korea, and China has 88, 70, 64, 60, and 45 patents on
average, respectively. Countries in East Asia and France have more non-commercial
assignees such as universities, institutes, and individuals. Non-commercial inventors
have contributed 59% of patent files in South Korea, 50% in China, 22% in France,
and 10% in Japan. This status highlights the fundamental role of research-based
organizations that receive financial assistance from governments in these countries.
